The Dish I Make for People Who Don’t Like Mushrooms

Everyone has that one friend. The one who insists they don’t like mushrooms. Who picks them out of everything, orders dishes without them, and makes a face when you mention you’re cooking with them.

This is the dish I make for that friend.

Oyster mushrooms are the gateway mushroom. Their texture is meaty and substantial without being slimy or intensely earthy the way creminis or portobellos can be. Their flavor is mild enough that it doesn’t announce itself the way a shiitake does, but present enough that it gives the finished dish something to build on. Battered and fried until shatteringly crispy, then tossed in a sauce that is simultaneously sweet, spicy, tangy, and savory, they become something that people eat without asking what’s in it and then go back for seconds before they’ve realized what just happened.

I’ve served this to mushroom skeptics more times than I can count. It works every time.

The Golden Lava Sauce

The sauce is the centerpiece of this dish and it earns that title. Built on a foundation of CHIN-SU fish sauce and CHIN-SU hot sauce, it hits four different flavor notes at once:

• Sweet from the sugar, which also helps the sauce cling to the crispy batter
• Spicy from the CHIN-SU hot sauce, which brings a bright, vinegary heat that builds without overwhelming
• Tangy from the fresh lime juice, which cuts through the richness of the fried mushrooms and keeps every bite feeling light
• Savory and funky from the fish sauce, which adds the kind of depth that makes a sauce taste like it has been cooking for hours when it has only been simmering for two minutes

The garlic gets sautéed until lightly browned before the sauce goes in, which adds a roasted, slightly nutty quality that raw garlic can’t deliver. The whole sauce comes together in under five minutes and is the kind of thing you’ll want to pour over everything once you’ve made it once.

Why Oyster Mushrooms

Oyster mushrooms have a few qualities that make them uniquely suited to this preparation:

• Texture — meaty and substantial enough to hold up inside the batter without disappearing, but tender enough to eat in one or two bites
• Surface area — their natural frilly, layered shape creates more surface area for the batter to adhere to, which means more crunch per piece
• Mild flavor — neutral enough to let the sauce do the talking without competing with it
• They fry beautifully — the moisture content is low enough that they crisp up quickly and stay crispy longer than most vegetables

If you’ve ever had Korean fried mushrooms or Japanese kakiage, this sits in a similar space but with a Southeast Asian flavor profile that makes it feel completely its own.

Sweet, Spicy, and Tangy Fried Oyster Mushrooms Recipe

Ingredients

Golden Lava Sauce

• 2 tbsp CHIN-SU Pho Quoc Fish Sauce
• 2 tbsp water
• 1 lime, juiced
• 3 tbsp CHIN-SU Hot Sauce
• 4 tsp sugar
• 2 tbsp garlic, minced

Mushrooms

• 200 g oyster mushrooms
• 150 g tempura or crispy fry flour
• 1 large egg
• 210 g ice water
• 2 tbsp green onions, finely chopped
• Neutral oil, for frying

---

Instructions

Step 1: Make the Batter

In a large bowl, combine the tempura flour, egg, ice water, and green onions. Mix until smooth with no lumps remaining. The batter should be thin and light, similar to a tempura batter. Keep it cold until you’re ready to fry.

Ice water is non-negotiable here. Cold batter hitting hot oil is what creates a light, crispy crust rather than a dense, doughy one.

---

Step 2: Coat the Mushrooms

Add the oyster mushrooms to the batter and toss until every piece is thoroughly coated. Make sure the batter gets into all the folds and crevices of the mushrooms.

---

Step 3: Fry

Heat at least 3 inches of neutral oil in a pot or wok to 350°F (177°C). Working in batches to avoid crowding, fry the mushrooms for about 5 minutes until deeply golden and shatteringly crispy. Remove and drain on a wire rack.

Do not crowd the pot. Overcrowding drops the oil temperature and results in soggy, oil-soaked mushrooms instead of crispy ones.

---

Step 4: Make the Golden Lava Sauce

In a small pot or pan over medium heat, add a splash of oil and sauté the minced garlic until lightly golden and fragrant, about 1 minute. Add the fish sauce, water, lime juice, hot sauce, and sugar.

Stir to combine and simmer for 1-2 minutes until the sauce has thickened slightly and the sugar has fully dissolved. Taste and adjust with more lime for acidity or more sugar to balance.

---

Step 5: Serve

Plate the crispy mushrooms and spoon the Golden Lava Sauce generously over the top, or serve it alongside as a dipping sauce. Either way, serve immediately while the crust is still crispy.

Tips

• Keep the batter cold throughout. If you’re frying in batches, keep the batter bowl over a bowl of ice between batches to maintain the temperature. Warm batter loses its ability to crisp up the way cold batter does.
• Fry in small batches. Patience here pays off. Crowding the oil is the single most common frying mistake and it results in steamed, soft mushrooms rather than crispy ones.
• Use a wire rack, not paper towels. Draining on a wire rack allows air to circulate underneath the mushrooms and keeps the bottom crust crispy. Paper towels trap steam and soften the crust.
• Serve immediately. The sauce will soften the crust over time. Get it on the table the moment it comes out of the oil for maximum crunch.
• Make extra sauce. You will want more than you think. It works as a dipping sauce, a drizzle over rice, or spooned over literally anything else on the table.

Serving Suggestions

Serve as a starter or snack on its own with the Golden Lava Sauce alongside for dipping. For a more complete meal, pile the mushrooms over steamed jasmine rice and spoon the sauce over the top so it soaks into the rice underneath. A simple cucumber salad alongside balances the heat and acidity of the sauce. Cold beer is strongly recommended.

Final Thoughts

The best way to change someone’s mind about an ingredient is to cook it in a way that doesn’t ask them to think about it. Nobody sits down to fried mushrooms in a sweet, spicy, tangy sauce and thinks about whether they like mushrooms. They just eat, and they keep eating, and somewhere between the second and third piece they’ve already converted without noticing.

Oyster mushrooms are the gateway. This sauce is the reason they stay.
